Apply Hazen William’s Equation to the pumped system shown in the following figure, having a pumping head of 77 mwc. Determine diameter of the pipe to deliver a flow of Q =4000 m 3 /hr maintaining pressure of 50 mwc at the entrance of the city through a pipe of L =1200m having Hazen William’s roughness coefficient C=120. Also calculate increase in the flow when the pressure at the entrance of the city drop to 40 mwc.

Two reservoirs A and B have elevations of 250 m and 100 m, respectively. It is connected by a pipe having adiameter of 250 mm and a length of 100 m. A turbine, with an efficiency of 0.95, which is installed at a point inbetween A and B, is used to supply 233 kW of electric power to a nearby community. If the total head loss as watertravelled from reservoir A to B is 25 m, determine the discharge inside the pipe in liters per second.
Find the work required to pump all of the water from a rectangular tank with an 8mx5m base and a height of 7m through a spout 1m high on the top of the tank. Assume water has a density of 1000kg per cubic meter and g=9.8 meters per second
The water needs of a small farm are to be met by pumping water from a well that can supply water continuously at a rate of 5 L/s. The water level in the well is 20 m below the ground level, and water is to be pumped to a large tank on a hill, which is 58 m above the ground level of the well, using 6-cm internal diameter plastic pipes. The required length of piping is measured to be 510 m, and the total minor loss coefficient due to the use of elbows, vanes, etc. is estimated to be 12. Taking the efficiency of the pump to be 75 percent, determine the rated power of the pump that needs to be purchased, in kW. The density and viscosity of water at anticipated operation conditions are taken to be 1000 kg/m3 and 0.00131 kg/m⋅s, respectively. Is it wise to purchase a suitable pump that meets the total power requirements, or is it necessary to also pay particular attention to the large elevation head in this case? Explain.
